Dual Junction Isolator
Ob chav sib cais cais yog ib qho khoom siv uas nquag siv nyob rau hauv microwave thiab millimeter-yoj zaus bands kom cais cov teeb liab cuam tshuam los ntawm tus kav hlau txais xov kawg.Nws yog tsim los ntawm cov qauv ntawm ob lub isolators.Nws qhov kev poob qis thiab kev sib cais feem ntau yog ob zaug ntawm ib qho kev cais tawm.Yog tias qhov kev sib cais ntawm ib qho kev sib cais yog 20dB, qhov kev sib cais ntawm ob chav sib cais feem ntau tuaj yeem yog 40dB.Qhov chaw nres nkoj sawv nthwv dej tsis hloov ntau.
Nyob rau hauv lub kaw lus, thaum lub xov tooj cua zaus teeb liab kis tau los ntawm qhov chaw nres nkoj input mus rau thawj lub nplhaib hlws ris, vim hais tias ib kawg ntawm thawj lub nplhaib hlws ris yog nruab nrog ib tug xov tooj cua zaus resistor, nws cov teeb liab tsuas yog kis tau mus rau lub input kawg ntawm lub thib ob. lub nplhaib sib txuas.Lub voj voog thib ob yog tib yam li thawj zaug, nrog RF resistors ntsia, lub teeb liab yuav dhau mus rau qhov chaw nres nkoj tso zis, thiab nws qhov kev sib cais yuav yog qhov sib npaug ntawm kev sib cais ntawm ob lub voj junctions.Lub teeb liab rov qab los ntawm qhov chaw nres nkoj tso zis yuav raug nqus los ntawm RF resistor nyob rau hauv lub nplhaib thib ob.Nyob rau hauv txoj kev no, ib tug loj degree ntawm kev sib cais ntawm cov input thiab output ports yog tiav, zoo txo kev xav thiab cuam tshuam nyob rau hauv lub system.
